Definición de saccade en inglés:

sustantivo

The pattern of fixations and saccades during visual exploration of a scene using only the eyes is strikingly similar to the intermittent locomotion of an animal searching for food in a physical landscape.

A reader's eye still moves in a series of jumps and stops known as saccades and fixations.

Also, in a variation of the boundary paradigm used in reading research, they obtained evidence that Chinese readers rely on phonological codes when integrating information across saccades.

The current analyses showed that response time, number of fixations per trial, initial saccadic latency, fixation duration, and saccadic amplitude varied as a function of the ratio between the red and blue items.
